It will fit many sizes of saw bases, indexing every inch. I forget what the large and small limits are, but it’s a pretty good base. Think I like most about it over the other bases is that it has four wheels instead of three, making for a bit more stability. Good luck, John.

I second the shopfox base. Specifically the heavy duty shop fox base. I use it for my unisaw and have absolutely no complaints. Plus it is considerably cheaper then the competition at 70 dollars or less (pending sales).
